NGSS HS-ESS1-1
The Standard
Develop a model based on evidence to illustrate the life span of the sun and the role of nuclear fusion in the sun's core to release energy that eventually reaches Earth in the form of radiation.

What This Standard Means
What Students Need to Do
- Students build and revise a visual model of the Sun from formation through its final white dwarf stage. They trace fusion-generated energy through the radiative and convective zones, then across space as electromagnetic radiation. They support model choices with observations of other stars and changes in solar activity.
What Mastery Looks Like
- A strong model correctly sequences formation, main sequence, red giant, planetary nebula, and white dwarf stages. Arrows show fusion in the core, radiation and convection inside the Sun, and electromagnetic radiation crossing space. The student uses stellar observations to justify the sequence.
Common Misconceptions
- Students may say the Sun burns fuel like a fire or that sunlight travels directly from the core to Earth. Some confuse energy transfer with matter moving outward, or treat sunspots as holes. They may predict a supernova, although the Sun lacks enough mass.
How to Assess It
- Exit ticket: Draw and label how energy moves from the Sun’s core to Earth. Add one sentence explaining how observations of other stars support the Sun’s predicted life span.

Ways to Teach It
Use colored beads, yarn, and a paper Sun cross-section to build a model tracing energy from the core to a solar panel.
Write: How can observations of stars with different masses and ages help us predict the Sun’s past and future?
Have teams race to sequence stage, evidence, and energy-transfer cards, then require one spoken justification for every match.
Compare a recent NOAA solar flare alert with GPS or radio reports, then explain how changing solar radiation can affect technology.
